Lucille Roybal-Allard - a 20-year Congressional incumbent - is headed to her first term in a newly drawn district in Tuesday's election.

With 100 percent of the 254 districts reporting, Roybal-Allard, received 59.4 percent of the vote compared to challenger David Sanchez, who received 40.6 percent of the vote, in unofficial results reported by the Secretary of State's Office.

Many residents are low-income, first-generation immigrants, according to the California Citizens Redistricting Commission.

Sanchez, a 62-year-old East Los Angeles resident and Los Angeles community college instructor, ran a non-traditional campaign by avoiding fundraisers and flooding the airwaves and mailboxes with campaign information. Sanchez also ran unsuccessfully against Roybal-Allard in 2010 in her previous 34th District.

Roybal-Allard, 71, who previously served three terms in the Assembly, is the daughter of late Congressman Edward R. Roybal, who served for 30 years.

First elected to office in 1993, Roybal-Allard was the first Mexican-American woman to serve in Congress.

In 2010, Roybal-Allard co-authored the DREAM Act, which would help undocumented immigrant youths become citizens if they enroll in college or enlist in the military.

As a senior member of the House Appropriations Committee, Roybal-Allard wields tremendous influence over how the U.S. government spends money.

She has pushed infrastructure spending as a road to job growth and to attract new industry. As a result, she helped secure $20 million for restoration and revitalization projects along the Los Angeles River, among other projects.
